Embodiment Construction

[0027] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the composition related to the present invention, and directions and references (for example, up, down, left, right, etc.) can only Used to aid in the description of features in a drawing. Accordingly, the following Detailed Description is not to be taken in a limiting sense, and the scope of claimed subject matter should be defined only by the appended claims and their equivalents.

[0028] See figure 1 with figure 2 , an underwater oil pipeline leakage detection device, the oil pipeline 1 is wrapped by an inner insulation layer 2 and an outer insulation layer 6 from the inside to the outside. There is an interlayer 3 between the inner insulation layer 2 and the outer insulation layer 6, and the inner insulatio...

Abstract

The invention relates to an underwater pipeline leakage detection device and method. An interlayer is arranged between insulating layers of an underwater oil transportation pipeline, multiple sectionsof calcium oxides (CaOs) wrapped by high-strength film are arranged in the interlayer, a partition is arranged between each section of the film, after the underwater pipeline leaks, the insulating layers are destroyed, the film wrapping the calcium oxides (CaOs) is destroyed, calcium hydroxide (Ca(OH)2) precipitation is generated in the interlayer after calcium oxide powder makes contact with water, a lot of heat is generated, and the specific formula is that CaO + H2O = Ca(OH)2) + a lot of heat. The temperature change is converted into a specific numerical change by a temperature sensor connected with the interlayer, and transmitted to the ground by a signal transmitter.

Description

technical field [0001] The invention relates to pipeline leakage detection technology, in particular to an underwater pipeline leakage detection device and method. Background technique [0002] Pipeline transportation has the advantages of continuous and efficient, safe and stable, economical and pollution-free, while underwater oil and gas pipelines can be continuously transported, almost unaffected by the environment, and the oil transportation efficiency is high. However, when the underwater pipeline leaks, if it cannot Stop leakage in time, because a large amount of oil leakage will cause serious environmental pollution and major economic losses, and the repair of underwater pipelines is difficult, so a leak detection technology for underwater pipelines is needed to detect and discover underwater pipelines in a timely manner leakage and take measures. Contents of the invention [0003] The object of the present invention is to solve the problems that it is difficult t...
